DisPass

DisPass is a password manager for GNU/Linux, *BSD, MacOS X and Windows.
It can be used as any traditional password manager, but has one key
difference. DisPass does not store your passwords anywhere, so you
can never lose them. It creates strong and unique passphrases formed
from a master password and a label (and some optional parameters),
helping you get rid of the bad habit of using a single password for
multiple websites. Dispass is a console application, but also has a
simple graphical interface.

Quick start

These are quick instructions for the impatient, just wanting to check
out DisPass. For full documentation on using DisPass, visit

Download

Download DisPass from the Python Package Index with pip. As root (using
sudo), do the following:

sudo pip install dispass

If you are using Archlinux, it is advised to install dispass
from the AUR.

Using DisPass for the first time

For this example we will create a passphrase to use for a google account.

Create and save a label google to the labelfile:

dispass add google

Generate the passphrase for the first time. Since you will need to
register the passphrase with google we pass the --verify flag
or simply -v to avoid typing errors in the input password while
creating the resulting passphrase for the first time:

dispass generate --verify google

Mini screencast

Checkout the following mini screencast. In this demo the label is added
interactively.

Software license

DisPass is released under an ISC license, which is functionally
equivalent to the simplified BSD and MIT/Expat licenses, with language
that was deemed unnecessary by the Berne convention removed.
